KNOXVILLE, Tenn. – The Virginia softball team (34-21) scored the lone run in the top of the fourth inning and held off Louisville’s seventh-inning threat to earn a 1-0 victory Friday in its NCAA Tournament debut.

Junior catcher Alison Pittman led off the fourth with a triple to the right centerfield gap and scored when the next batter, senior Abby Snyder, hit a groundball to Louisville second baseman Jordan Trimble. Trimble’s throw to home plate was on the mark but Pittman beat the tag to score what proved to be the game-winning run.

The Cavaliers move on to face the winner of the Ball State vs. Tennessee matchup at 1 p.m. Saturday at Sherri Parker Lee Stadium in Knoxville.

Mitchell threw all seven innings, allowing four Louisville hits. She finished with six strikeouts.

The next batter, Melissa Roth, was walked for the third consecutive time to put runners on first and second with one out.

Mitchell did not rattle and came through for a big out after striking out pinch hitter Brittany York. With two down, Chelsea Bemis walked to load the bases. Mitchell then caught Colby Wherry’s lineout back to her to end the game.
